Abstract

(57) [Summary] [PROBLEMS] The material of the outer casing of the product itself is less limited, and the texture and value of the product can be improved by using the metal outer casing, and the shielding effect of the outer casing is improved. The effects of the internal electric circuit elements of the antenna module can be greatly reduced, favorable communication effects can be obtained, and the use of antenna pads is eliminated in product design, so that costs can be reduced and product design can be simplified. It can be formed to be short and small. SOLUTION: An antenna housing portion and a through-hole are formed at an appropriate place in an outer casing of a communication product, and the planar antenna is recessed in the antenna casing so as to be integrated by a grill or the like. The through hole is provided for connecting the antenna and a radio frequency electric circuit module of an electric circuit board.

[Technical field to which the device belongs]

  The present invention relates to a wideband antenna assembly, especially for home and personal use. Bluetooth (registered trademark) such as line communication products and wireless areas Wideband used according to needs such as regional network and home radio frequency By implementing improved designs for antenna module systems, manufacturers Greater freedom and improved communication effects when planning or designing products The present invention relates to a wideband antenna assembly that can be obtained.

[0002]

[Prior art and its problems]

  At the moment, wireless communication products for home and personal use, such as notebook Wide that can be attached to a personal computer or PDA (personal digital assistant) In case of band antenna module, as shown in Fig. 1, all are flat antennas. The design of (10) is adopted. Prearranged on the lower surface of the planar antenna (10) The antenna pad (101) is provided and the electric circuit board body (3 0) and the antenna contact (302) of the electric circuit board body (30) Via the radio frequency electric circuit module (301). However, this In the case of a design such as Will significantly reduce the communication effect, and as a result, operators will frequently It is necessary to increase the height of the antenna pad (101) to reduce the inferior effect. Often leads to waste of design space and improvement of manufacturing cost, and One antenna module needs to be assembled inside the product, so the external case of the product The design of the material of the ring (20) has a fairly large limit (metal material having a shielding effect). Quality cannot be adopted) and the product quality may be deteriorated.

[0003]   The present invention implements another design for the wideband antenna of the same property. This allows manufacturers of wireless communication products for home and personal use to The design of the structure of the antenna assembly pushes the limits in the design of the immediate product. User-friendly and effective, aiming to break and eliminate economic disadvantages Its main goal is to provide better home or personal wireless communication products. To aim.

[0004]

[Means for Solving the Problems]

  The present invention provides a wideband antenna assembly, which can be used as an external cable for the communication product. The antenna housing and the through hole are formed at appropriate points in the Dangle the tena into the antenna casing so that It is placed in the antenna housing formed by the It is provided for connection with a radio frequency electric circuit module on a circuit board. like this There is not much restriction on the material of the outer casing of the product itself, and the outer casing made of metal is used. The quality of the product and its value can be improved by adopting Due to the large shielding effect of the antenna, the internal electric circuit elements of the antenna module It is possible to significantly reduce the influence of the communication, and obtain a favorable communication effect. Also, for product design Eliminates the use of antenna pads, reducing costs and designing products It can be made light, thin, short and small.

[0005]   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. .

[0006]

[Embodiment of device]

  The wideband antenna assembly designed according to the present invention is mainly designed as shown in FIG. It consists of the surface antenna (1) body and the outer casing (2), of which assembling In this case, the planar antenna (1) is installed in the outer casing (2) with a preset antenna. Attach it to the tenor housing (21) and attach one end of the planar antenna (1) to the antenna. By passing through the through hole (22) of the storage section (21), the electric circuit board The board main body (3) is connected to the radio frequency electric circuit module (31).

[0007]   The type of the planar antenna (1) designed according to the present invention is also a printable planar antenna (1 ') ( 4) can be adopted, which directly connects the printed planar antenna (1 ') to the external cable. It is printed on the antenna housing part (21 ') of the single (2'). A local surface treatment should be performed before the sing (2 ') is printed, which To provide an insulating structure between the printed planar antenna (1 ') and the outer casing (2'). This is another embodiment.
